Abstract (en)

[origin: EP3109645A1] A microcomputer section (23) operates by use of electric power from a power supply section (21). The microcomputer section (23) carries out control so that any one of a plurality of switching circuits (20) is selected, the selected one of the plurality of switching circuits (20) causes an electric current from a corresponding current transformer (CT) of a plurality of current transformers (CT) to flow to the microcomputer section (23), whereas the other unselected switching circuits (20) cause electric currents from respective current transformers (CT) of the plurality of current transformers (CT) to flow to the power supply section (21), and the selection is carried out successively with respect to each of the plurality of switching circuits (20).
